RING FOR PIPE-COUPLINGS.

Specification of Letters Patent.

Application filed November 10, 1905. Serial No. 286,649.

To all whom it may concern.-

Be it known that 1, WILLIAM W. PRICE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Rings for Pipe-Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom- 'panying drawings, and to the figures of referthe parts are united are as is shown in the acform flanges 3 and 4.

companying drawings.

The object of the invention is to provide a superior coupling-ring in point of strength, while at the same time the manufacture of the ring is expedited to a degree which materially decreases the cost thereof.

Preceding a detail description of the invention reference is made to the accompanying drawings, of which- Figure 1 is a bottom plan view of my improved two-part coupling-ring, a portion being broken away. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is a side elevation.

In a detail description of the invention, similar reference characters indicate corresponding parts.

The coupling-ring, as before stated, is essentially constructed of pressed steel or plate of suitable thickness, depending upon the size or diameter thereof, and consisting of two united members 1 and 2. The requisite dies being provided, the inner member 1 is given the form shown in the drawings, which consists of a cylindrical body with its ends turned laterally in opposite directions to The width of the flange 8 is essentially greater than that of flange 4, and the flange havin the greater width extends inwardly, whi e the outer flange 4 need only be of sufficient width to provide the necessary bend 5 to tie the outer member of the ring with the inner member at that point. The said flange 4 is cut out, as at 4, at suitable points to provide spaces for the passage of the bolts. The outer member 2 is likewise pressed into the requisite form by means of suitable dies, and when given such form it has a tapering wall and the inwardly-extending wall or flange 2. This outer member of the ring engages the inner member at two points-to wit, upon the flange 4, as before stated, and upon the flange 3. The extreme edge 6 of the flange 2 of said outer member is bent over the edge of flange 3, and thus the two parts become locked to each other, and the parts of the ring are thus prevented from separating under the strain due to the bolts. The lockingpoints between the two members, which hold them rigidly together, are, as before stated, at 5 and 6. The outer member 2 is provided in its strai ht portion 2 with a series of bolt- I-atented. May 22, i

holes 7 an in its inclined portion with a series of slots or openings 8, which permit of the passage of the bolts when inserted through the holes 7. These bolts, which are not shown, unite two of the coupling-rings when effecting a joint or connection between two sect-ions of piping, it being understood that two such rings are employed for each coupling or pipe joint, both rings being duplicates. It will be understood that the purpose and function of the part constituting the outer member of the ring is to provide the proper reinforcing strength to the inner member and 0 1provide a place for the attachment of the Having described my invention, I claim- 1. A pipe-coupling ring, consistin of two members formed from sheet metal, he inner member having inwardly and outwardly extended flanges, and the outer member having a tapering wall which is supported and secured upon the outer flange of said inner member, and an inwardly projecting wall which is supported and secured upon the inner flange of the inner member, said outer member having two series of bolt-holes, substantially as specified.

2. A coupling-ring for pipe-j oints, the same being formed from sheet metal and consisting of two assembled members, the inner member having its edges turned in opposite directions and providing inner and outer laterally-extending flanges, the inner flange being of greater width, the outer member having a portion thereof disposed on a suitable slots within which the bolts penetrating said 10 incline to engage the outer flange of the inner bolt-holes, lie, substantially as specified. member Where it is rigidly secured, and the In testimony whereof I affix my signature other porgilon ofd said outer IIlnember rojeot in presence of two Witnesses.
